First of all, it looks like a repurposed Galaxy S4, with small changes to the back plate near the bottom of the device. Volume rocker and power/lock buttons are in familiar places for Samsung users. We would not be surprised if that was a 13MP camera.
Specification-wise, we do not know anything official, but this form factor virtually guarantees the aforementioned camera, a 5-inch 1080p display, 2GB of RAM, and we fairly certain that there is a quad-core Qualcomm Snapdragon CPU to round up the package.
Samsung ATIV S, the ATIV SE has a physical home button, but what is most visibly missing is the dedicated camera button along the lower right side of the device. That means that Microsoft had let the manufacturers know quite a long time ago that some Windows Phone requirements in form factor were going to be loosened.
The Galaxy S4 is a great set-up and does not feel out of place even amongst today’s flagships. That chassis will certainly serve Samsung and Windows Phone well.
